AUTOMATIC HYDROCARBON-FEEDING APPARATUS FOR C'ARBURETORS.

SPECIFICATION forming part of Letters Patent No. 308,877, dated December9, 1884.

Application filed April 28, 1884. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES F; COPELAND, a citizen of the United States,residing at Boston, in the county of Suffolk and State of Massachusetts,have invented certain new and useful Improvements in AutomaticHydrocarbon- Feeding Apparatus for Carburetors and I do hereby declarethat the same are fully describedin the following-specification andillus trated in the accompanying drawings.

This invention relates to improvements in automatic hydrocarbon-feedingapparatus for supplying hydrocarbon to gas machines or carburetors; andit is carried out as follows, reference beinghad to the accompanyingdrawings, where-- v Figure 1 represents an end View of the invention,and Fig. 2 represents a central longitudinal section on the line A BinFig. 1. Fig. 3 represents a cross-section on the line C D in Fig. 2, asseen from the right end of said Fig.

. 2; and Fig. i also represents a cross-section on the line C D, as seenfrom the left end of Fig.2.

Similar letters refer to similar parts wherever they occur on thedifferent parts of the drawings.

a is the cylinder, within which is located the rotary motor b, havingthe screw-shaped wing b, and arranged upon the central shaft or spindle,b, located in suitable bearings in the cylinder a, as usual.

0 is the gas-supply pipe leading to the motor I), and terminating withinthe latter as the upwardly-projecting pipe 0, as usual.

dis a branch pipe connected to the gas-supply pipe C in the ordinarymanner, through which atmospheric air is forced with the gas into andthrough the motor I).

e represents the hydrocarbon within the cylinder or case a, suchhydrocarbon being kept at a proper level above the motor-shaft b, asshown in Fig. 2, by a suitable float regulating device.

To one end of cylinder at is attached the box or chamber f, the upperportion of which is in open communication with the cylinder a by meansof the opening a, made through the end of cylinder a where the box f isattached, as shown in Figs. 2 and 3, to allow the gas and air to passfrom the cylinder at and its motor 1) into the upper part of the chamberf. The

lower part of said chamber f is in open communication with that part ofcylinder a containing the hydrocarbon by means of the perforation f,(shown in Fig. 3,) so as to keep the hydrocarbon g in chamber f on alevel with the hydrocarbon e in cylinder at in the ordinary manner.

h is the hydrocarbon-supply pipe leading to chamber f, and connected onthe inside of the latter with a valve-box, 72., having valve h,delivery-opening h, valve-spindle If, hinged lever h, stationaryfulcrum-support h, and

' float if, in the usual manner, for regulating the supply ofhydrocarbon, and to retain its upper level at a normal one during theoperation of the apparatus.

WVithin the box f is located upon the end of motor-spindle b the smallpinion b ,that gears into the teeth of gear-wheel z, secured to thespindle i, that is free to move in suitable bean ings within the box f,as shown in Fig. 2.

To the spindle i is secured the disk, rim, or wheel k,having pivoted toits peripheral spindles 70 k the movable buckets 70" k, as shown inFigs. 2 and 4.

Above the spindle z" is secured to the wall of chamber f the spring-barZ, (shown in Figs. 2 and 4,) that serves for the purpose ofautomatically tipping over each bucket 70" when it reaches its highest,or nearly so, position, and to deliver the hydrocarbon from such bucketinto the trough an after it is taken up from the contents of chamber f,when such bucket passes through the liquid contents of said chamber, asrepresented insaid Figs. 2 and 4.

The trough m communicates with the downwardly-projecting pipe n, thatleads to the car: buretor, and by this means a constant supply ofhydrocarbon is taken up by the pivoted revolving buckets 7c", anddelivered through the pipe at to the carburetor,where the gas or air isto be enriched. The upper end of pipe at opens into the upper portion ofchamber f, so as to allow the gas and air forced from the motor 1) intosaid chamber to pass down through said pipe at with the hydrocarbonsupplied from the buckets k 7a.

The operation of the apparatus is as follows: Air and gas being forcedinto the cylinder a by means of the pipes c d, and made to pass throughthe upper portion of motor 12, the latter is caused to rotate around itsaxis, and by spindle 12, wheel k, with its pivoted buckets means of thegears b i a rotary motion is im- 7c k, spring Z, trough'm, delivery-pipen, hyparted to the wheel k, causing its pivoted drocarbon-supply pipeh,wit11 its valve h h, 15 buckets 7c 70 to dip into the hydrocarbon ginlever h and float h, all arranged and com- 5 box f, and to take upaportion of such hydrobined in a manner substantially as set forthcarbon, and to empty it into the trough m as and described. the bucketssuccessively come in contact with In testimony whereof I have affixed mysigthe tipping-spring Z, as described. nature in presence oftwowitnesses.
